If shutter delay prevents this "resonance" then it has to be caused by the mirror rather than shutter activation.

Robin, would you elaborate on this a bit?

I found on my 800 that at lower shutter speeds <1/100 that shutter delay does indeed make the image sharper. I found this when fine tuning and noticed CDAF was consistently sharper than PDAF. Someone suggested that I try shutter delay or increase the shutter speed. Either corrected the problem.

My question - I thought shutter activation occurred when the mirror went up and down. Is shutter activation instead just the capture of the image that the sensor is seeing while the mirror is the physical movement of same? That is, shutter activation is more of an electronic action?

What's to elaborate on?  In shutter delay the mirror goes up when you first press the shutter release button.  There is then a delay before the shutter curtain is activated.  This allows for mirror vibrations to dampen out.  Finally, the shutter curtain is opened and a photo is taken.
